Public policy can encourage this bursting bubble scenario. The Democrats want to tax the oil companies or use the antitrust laws against them. Big mistake. More taxes get you LESS oil and "concentration" in the oil industry is not really the problem. The on-going Congressional hearings "investigating" oil prices and profits is a charade and is purely political theater. The very same federal and state governments that complain about high oil prices continue to tax gasoline at a rate (40 cents per gallon) far higher than the profit rate for the oil companies. So much for government concern about consumers.
What was it that Ronald Reagan said were the scariest words you could hear? "I'm from the government, and I'm here to help."
